Olfactory-auditory sensory integration in the olfactory tubercle. Bar graphs of average stimulus evoked responses across 17 units in response to tone (left), odor (middle, see methods for odor) and simultaneous tone and odor presentations (right column).hus, both accessory and main olfactory systems converge in the olfactory tubercleâpresenting this structure as a âmixedâ olfactory cortex (Martinez-Marcos, 2009). These anatomical points highlight the likely role of the tubercle in the processing of odors.
Precancerous condition. A precancerous condition or premalignant condition, sometimes called a potentially precancerous condition or potentially premalignant condition, is a state of disordered morphology of cells that is associated with an increased risk of cancer. If left untreated, these conditions may lead to cancer.
A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predispose the affected individuals to the development of cancers and may also cause the early onset of these cancers.any of these syndromes are caused by mutations in tumor suppressor genes, genes that are involved in protecting the cell from turning cancerous. Other genes that may be affected are DNA repair genes, oncogenes and genes involved in the production of blood vessels (angiogenesis).
